Sections

For 30 years of making air purifiers, Winix has been a leader in Asian air purifier market, and its hand has even reached the border of the U.S since 2004. Just like the other Korean rival – Coway, this air purifier brand is likely to upgrade the old devices into new one, while keeping the old appearance. The Winix 6300-2 is one air purifier like that, and we will check this device thoroughly with our Winix 6300-2 Review.

Winix 6300-2 Price

It seems these recent years are the time for Winix to improve its old air purifiers. The company upsells its new products in order to replace the old ones. For example, the Signature Series Winix U300 and Winix U450 are meant to replace the old Winix P300 and Winix P450. Things happen the same with the new Winix C555 and Winix 6300-2, to replace the most popular trio of this brand, the Winix 5300-2, Winix 5500-2 and Winix C535.

But Winix still can’t drop the messy naming regime, and what could we expect at the moment, the Winix C545, or Winix 6500-2? It is easy to confuse even the most loyal customer of Winix, and therefore you need our reviews to help you distinguish one air purifier from another.

After the launch of the Winix Signature Series, it is safe to conclude that the new Winix 6300-2 and Winix C555 will only increase the price of the previous models a little bit, for around $20 more. The official price of the Winix 6300-2 is $219, compared with the price tag of the Winix HR900 and Winix C545. This is also the same price on sale of the new Winix U300, as well as many mid-range devices that is continuously dropped to be budget like the Winix HR950 or Winix HR1000. With such strong base, the Korean company is now undeniably one of the most popular air purifier brands in the U.S market.

But Coway has also responded with the Coway AP-1512HH, Airmega 200M and Airmega 250. These air purifiers are always high on our lists, especially the former. You know you can’t go wrong with the best air purifier that is recommended by Breathe Quality, right? Other air purifiers with the same price can be considered are the Honeywell HPA300, AeraMax 300, Medify MA-40 and Blue Pure 211.

If you are in the U.S, you will find the Winix 6300-2 for sale on Amazon. Let’s grab the below deal.

Winix 6300-2 Design and Size

Like I said earlier, the point to release the Winix 6300-2 is maintaining the old design of Winix 5500-2, and just only change the internals. Come on, so we are still looking at a very old model at the moment…

If it ain’t broke, don’t fix. It seems the Winix 6300-2 follows the rule strictly with not a slight change from the previous Winix 5500-2. The build quality is still standard with the plastic body, as well as a small but stable base to keep it on ground. The color option of the Winix 6300-2 is black tinted, just like the model Winix 5500-2.

So far, Winix continues to keep up with the bottom-to-top airflow system. This is also my favorite airflow concept for a compact air purifier, just like the Winix 6300-2. Mentioning about the size, the Winix 6300-2 is only 23.6 inches in height, which is another similarity to the predecessors.

On top of this Winix 6300-2, the control panel remains the same, too. It quite leans on top, to help you press the buttons much easier than the old model Winix WAC6300 or Winix WAC9500. You can find here the air sensor and LED light indicator of this Winix 6300-2.

So to say, Winix 6300-2 weighs the same with only 15.4 lbs. If you are familiar with the design concept of old Winix products, you will know it is simple to move the Winix 6300-2 around your home with the built-in handles.

Winix 6300-2 Filters

The reason you search for the Winix 6300-2 instead of the old Winix 5300-2 is mostly because of the next-gen air filtration system. And here you are, the new 4-stage air cleaning system of the Winix 6300-2.

1. Pre-filter – The polluted air must first pass through a fine mesh pre-filter. This pre-filter will help capture the large objects of contaminants, such as pet hair and even some kinds of pet dander and skin.
2. Activated Carbon filter – The carbon sheet filter is the same as old devices, which offers odor protection against household odors from cooking, pets and smoke, as well as adsorbs the chemicals and VOCs.
3. True HEPA filter – The True HEPA Filter that captures 99.97% of as small as 0.3 microns allergens, virus particles, pollen, mold and fungi particles.
4. Winix PlasmaWave – This technology is one kind of ionizer, which can further reduce the amount of pollutants. Can be switched on/off.

Well, with the new fine mesh pre-filter, the Winix 6300-2 can capture the large objects of pollutants more efficiently. As a result, the pre-filter can reduce the stock of the large particles on the surface of HEPA filter, to prolong its lifetime (the larger objects can destroy the fibers of HEPA filter quickly). While it is a well-built air filter, the True HEPA filter of the Winix 6300-2 still can only last for 1 year, just like the old Winix 5300-2 and Winix 5500-2.

I don’t want to repeat more about the combination of True HEPA filter and PlasmaWave technology. You just need to know that this is one of the most comprehensive air filtration systems at the moment, and you can learn more about the PlasmaWave technology here.

I used the same test of the Winix 5300-2 to apply into the Winix 6300-2, meaning this air purifier needs to run in a room of 200 square feet for 1 hour. I still use the Honeywell 50250 and Honeywell AirGenius 4 as the challengers of the Winix 6300-2. The result, this Winix 6300-2 can deal with 99.95% of all particles down to 0.3 microns, which is better than the Honeywell 50250. The Honeywell AirGenius 4 has an efficiency of only 92%.

You can also look at the chart below to compare the performance of this Winix 6300-2 with many popular air purifiers at the moment, like the Oransi OV200 or Honeywell HPA300.

Sadly, the filter replacement cost is disappointing, as it is $69. You should know Winix is selling the refurbished Winix 6300-2 for only $89, and the high filter cost is still one of the main obstacles to keep you from buying Winix air purifiers.

Winix 6300-2 Room Coverage

With so many similarity both inside and outside, I know that the Winix 6300-2 can’t exceed the predecessors in terms of fan power. So this air purifier is mostly suitable for a room of 360 square feet, which is quite similar to the GermGuardian AC5900W and even Philips 2000i.

The ACH of Winix 6300-2 is 4X. The Winix 6300-2 will exchange the air in your room once every 15 minutes.

The CADR of Winix 6300-2 is 243 Dust/ 232 Smoke/ 246 Pollen (cfm). It is great among the Winix lineup, but it is nowhere near the Honeywell HPA300 and Blue Pure 211 for the same price.

Winix 6300-2 Sound

Same fan power will release the same noise level, and that’s why you can easily know the noise level of the Winix 6300-2 to be just 28 decibels (dB).

Winix is an air purifier brand with fame in making low noise level air purifiers. Even with a much better fan power, this company improves the fan to reduce the noise level as low as possible. This is also the effort Winix tries to do to reduce the ozone emission from its PlasmaWave technology.

If you plan to run this Winix 6300-2 in your bedroom or your office, I believe that you won’t be distracted by the noise it makes.

Winix 6300-2 Power Consumption

One of our most FAQs is “Do air purifiers use a lot of energy?” In fact, air purifier must be used for a long time to be efficient. And power consumption is one important criteria to review if this air purifier is good or not.

Again, with the same materials to make the air purifier, the Winix 6300-2 has a power consumption of about 70 watts. Of course, it is higher than others in the low-range market, like the Levoit LV-PUR131 only run with 40 watts, or the Honeywell AirGenius 4 with maximum of 38 watts. So to say, it costs you much more in the long-term running with this Winix 6300-2.

For using the Winix 6300-2 8 hours per day, it would cost you about $25 per year. You should know the Winix 6300-2 is an air purifier with Energy Star rating, and though it has higher power consumption, it would cost you only $0.07 per day to keep your air clean.

Winix 6300-2 Additional Features

So far, Winix is the pioneer in adding the air sensor into even the budget air purifier like Winix P150. We don’t need to ask for the Smart Sensor in the Winix 6300-2, because it is the must-have feature of this brand.

Well, it is the same air sensor that is built in the Winix 5300-2 and Winix 5500-2. Every time it detects the change in your indoor air quality, it will notify you via a beautiful LED indicator. Moreover, if you are running your Winix 6300-2 in Auto Mode, it can automatically adjust the fan speed to match the environment. With this function, you don’t need the remote control anymore. You only need to turn on the air purifier, and forget it.

If you are fond of the Wi-Fi Enabled Connectivity feature, you should look for the Winix C545 and Winix AM90 instead, as they both offer this high-end feature while keeping the price to be nearly the same as the Winix 6300-2.

Also, you will have a remote control to help you control your unit even in your couch. This convenient thing is not available in Winix 5300-2, though.

Just like the Winix C535 and Winix C555, our Winix 6300-2 features the basic Timer and one LED indicator for filter replacement.

Our verdict

After many tests, I can safely conclude that the fine mesh pre-filter does improve the efficiency of the Winix 6300-2. But the result is not significant compared with the older devices like Winix 5300-2 and Winix 5500-2, so if you can’t grab a really good deal of the Winix 6300-2, you can turn for these aforementioned air purifiers as well.
